These commands will mount the volume using the loopback device. kpartx is used to create mappings for all partitions

create a new Linux virtual machine with the same kernel and linux version. We will call this instance INSTANCE2. For Ubuntu you can find them at: http://cloud-images.ubuntu.com/locator/ec2/. We are using in this case ami-09bea87d (Ubuntu 11.10).

stop INSTANCE2, detach the volume and attach this volume (the root) to INSTANCE1. Mount the volume to /mnt/dest.

mkdir /mnt/dest
mount /dev/sdb1 /mnt/dest

attach the volume you imported and mount it to /mnt/src.

mkdir /mnt/src
mount /dev/sdc1 /mnt/src

copy all files of the filesystem from /mnt/src to /mnt/dest, except for the boot and dev folders.
